Hi Guys... I have mostly just used Link Clicks or Clicks (deprecated now) as the optimization for ad delivery.. But lately performance on new ads has been complete shit with ridiculous CPCs... I tried Daily Unique Reach and Impressions before but the CTRs drop and CPCs shoot up I've always been paranoid with using FB's pixel for Conversions but I think its time to make the leap... For those of you that have tried it, how effective is it? Does optimization for Conversions usually outperform Link Clicks?
